Thanks I_Withnail
I have not tried this as yet but thanks for the info, I do have another question though. If I do this on the phone will all my previously purchaced apps continue to run on the phone? I'm guessing [hopeing] yes. I actualy have three devices, an iTouch first gen 32 gigs which is updated to v3.12, a 16 gig 3g updated to v3.0 and a 3g 8 gig it's at 2.21 I think.
Thanks again!
