Setting up a Bluetooth modem connection for the Nokia E60/61/62 or E70 is quite easy with T-mobile. You don't need to download anything extra.
Note that if you are planning on buying the E62 for T-mobile use, don't. It's almost the same as the E61, but it's been changed so UTMS will only work on Cingular's network, and you won't be able to use UTMS when TMO rolls it out.
Onto the goodies:
Add the phone from the Bluetooth preference pane in System Preferences
Configure the phone to dial a modem, NOT a GPRS provider
The default Nokia Infrared script works fine.
For the access number, enter *99***1#
Go to Internet Connect under the Bluetooth tab and press Connect.
You should also note that you will probably have to purchase the unlimited internet access for this to work.
Here's how to set up your Mac to use a Nokia e62 as a Bluetooth modem with Cingular. I'll bet this works on lots of other Bluetooth phones as well. Although there's an existing hint covering a similar topic, some of the newer phones use slightly (but critically) different configurations. This blog entry ended up being the most useful for me.
While trying to get my Nokia 6126 to work with iSync (it is not supported at the time of writing) I came across some info at chromewalker.com about getting a 6131 to work. Since the 6126 is essentially a 6131 but for North America, I gave it a try and it worked.
Make sure iSync is not running, and un-pair the phone from your Bluetooth preferences.
Go to your applications folder and right click on the iSync application.
Within this last folder there will be a file called Metaclasses.plist
Copy this file and rename it something like Metaclasses.plist.bkp, if you do not know how to do this, you shouldn't even be trying this.
Once you have made a backup of the file, open the original file in a text editor and do a search for the Nokia 6111. When you find it, you will see that it is a Series 40 v3 device.
Look at all the stuff that precedes it and follows it and make sure to copy only the stuff that pertains to the Nokia 6111 and copy/paste it right below it. This will give you two Nokia 6111's in a row. Then on the second Nokia 6111 change every instance of the 6111 with a 6126 and save the file.
Pair the phone with your mac, and then launch isync.
There is a known bug in iSync which prevents repeating events starting earlier than 1980 from syncing to Symbian OS devices (such as my Nokia N80). Since birthdays entered into the Address Book will often have starting dates prior to 1980, this means they won't show up on your phone. Annoying.
Here's a small AppleScript I wrote to create a copy of the Birthdays auto-calendar in iCal, resetting the start dates of any early birthdays to 1980. If you save the script to ~/Library -> Scripts -> Applications -> iCal, and install the AppleScript menu item, you'll be able to create and update your syncing calendar with ease. All you need then do is select the correct calendar for syncing in iSync.
I made my own iSync plug-in for the Sony Ericsson K800i, and thought I'd share it [20kb download]. The calendar and phone book both work perfectly well with this plug-in. Extract the tar file into /Library -> PhonePlugins. If you don't have a PhonePlugins folder in /Library folder, then create it first.
Then just pair your device with the computer and then start up iSync. When you add a new device, it should detect your phone and should say it's supported. Hope it works for you too!
Both Verizon and Sprint offer the use of the Treo 700p as a Bluetooth modem for a monthly access fee. Reportedly, if you use too much data transfer, they'll shut you down.
After endlessly searching for a way to use my phone as a modem without working through Verizon, I came across USB Modem, which not only allows you to use the Treo as a modem, but also utilizes the faster USB connection. Only the Treo 700p offers speedy broadband access; reportedly 10x faster than dial-up; I don't know how fast pages load with the 600 or 650. And BTW, it syncs flawlessly with Apple's Palm iSync conduit.
[robg adds: I haven't tested this software, and note that it's $24.95 -- however, there is a demo version you can test to make sure it works for you prior to purchasing. Please keep in mind that you are responsible for anything you do to your phone, and/or anything that your service provider may then do as a follow-up to your actions.]
Want to add support for your Nokia N91 to iSync? Here's how. In the Finder, control-click on the iSync application and choose Show Package Contents. Then navigate into Contents -> Plugins -> ApplePhoneConduit.syncdevice -> Contents -> Plugins -> PhoneModelsSync.phoneplugin -> Contents -> Resources. In that folder, modify MetaClasses.plist (make a backup first!) using the below code.
Following in others' footsteps, I played around and got my new Nokia 6103 from T-Mobile to sync with iSync. As in the previous hint, navigate into the iSync package (control-click, Show Package Contents, then drill down to Contents -> PlugIns -> ApplePhoneConduit.syncdevice -> Contents -> PlugIns -> PhoneModelsSync.phoneplugin -> Contents -> Resources), and then edit the MetaClasses.plist file.
Since the E61 is the latest mobile phone/PDA device from Nokia, and it's still a new thing, there is no iSync support yet (although Bluetooth pairing and browsing the device works just fine). So here is what you have to do to enable basic syncing of contacts and calendars/ with iSync Version 2.2.
I bought a new Nokia E70 recently, and of course, iSync doesn't support it yet, so I did a little hacking and got it working. You can read all the details, including info on fixing a timezone offset issue, in this entry on my blog. Read on for the required edits to MetaClasses.plist.
