I upgraded yesterday my 1st generation iPhone to FW2.0 5a225c (using it with t-mobile). The reason fort he upgrade is because i really need exchange support!
I noticed that after the upgarde, the iPhone is running slow! sometimes it takes up to 30 seconds to load the sms menu or anything else!!!!
any idea why? is it cause the FW is not the final release???
Thanks for all the help!
