iPhone 3.0 Beta 4 Bluetooth tethering results: Less than 1/3 the speed of USB
April 29th, 2009 • 1 comment Apple, Internet, iPhone
So, it’s rather slower – 96kbps.
To test it, i tried the ThinkBroadband speed tester, (that i successfully used to test USB tethering), but it failed to complete the test.
I then tried the Broadband speed tester site and got the above results, as well as a 74kbps upload speed.
When (if!) i find time, i’ll go digging and find out if there’s an obvious reason for this – it’s clearly shouldn’t be bottlenecked by the performance of BlueTooth, as it should run up to 3 Mbit/s (http://en.wikipedia.org/wiki/Bluetooth)
iPhone 3.0 Beta 4 + iTunes 8.2 Pre-release = USB Tethering Active Again :)
April 29th, 2009 • Apple, Internet, iPhone
Yep, USB tethering died in Betas 2 and 3, but with iTunes 8.2 Pre-release and Beta 4, all is working again and it feels wonderfully fast. Well, it’s only running at 336.58 Kbps, but it feels great! As a note, i think the fix was actually iTunes rather than iPhone Beta 4.
Lovely 
Now to test the Bluetooth speeds

A point worth noting by all iPhone developers considering the exciting opportunities of cloud-side iPhone app notifications – how much will it cost you to provide this service?
An important point to consider.
iPhone 3.0 beta 2 tethering how to
April 3rd, 2009 • 9 comments Apple, Internet, Mac, iPhone
In iPhone 3.0 beta 1, tethering didn’t work. In beta 2, it does and it’s really simple to achieve. It does require a quick mod to your iPhone. Here’s what you have to do:
1. Download the o2_uk.ipcc carrier details file. Please note that this is the UK ipcc file. If you’re not on O2 in the UK, search google for your suitable ipcc file.
2. Connect iPhone to PC / Mac and select to restore with the option to select a custom restore package (hold down option on Mac before selecting restore)
3. Select the ipcc file as the restore package. The change of details on the phone takes only a few seconds and doesn’t require an iPhone reboot
4. Go into iPhone Settings app > General > Network > Internet Tethering and enable.
5. Connect iPhone to PC / Mac over USB or bluetooth
6. The PC / Mac will do the rest
7. Done!
Works great (i’m posting via tethering now)
