DevTeam says that 2.2 update SHOULD NOT be applied using iTunes if you want the chance of a soft-unlock in the near future. Use new version of PwnageTool (not avaliable yet, but will be soon).
Some fact:
The 2.2 firmware for 3G contains a baseband update for the 3G iPhone
The 2.2 firmware for 2G (1st gen iPhones) doesn’t contain a baseband update and the baseband is still at 04.05.04
Pwnage technique (and therefore the Jailbreak) isn’t affected, but PwnageTool and QuickPwn do not support this release as yet, so DO NOT install 2.2 using iTunes as you will lose your jailbreak
News from DevTeam, they try to unlock iPhone 3G for a long time already:
"This ability we now have to spawn background tasks means we are one step closer to the 3G soft unlock. We have a clear path to follow, and “all” that remains is the implementation." Watch the video:
This is the 5th step in the following achievements:
Citrix is porting XenApp to the iPhone. XenApp is a remote Windows application that is presently available for Mac, Windows and some mobile platforms. XenApp allows users to remotely log into their corporate networks to access their Windows applications.
The functionality seems similar to existing VNC clients for the iPhone, but Citrix's XenApp apparently transmits window display information rather than the raw graphics (wikipedia link). This is much better than VNC over network connections such as 3G and WiFi.
Michael Koppelman is an iPhone developer and model rocket enthusiast. He decided that combining his two hobbies together would be a good idea. He created an app that constantly polled the iPhone’s GPS and accelerometers, logging them to a file and then transmitting the data from the GPS over the web so that the unit could be located if it became lost.
