i was browsing in safari yesterday and my phone froze up. upon restarting, it goes to the "connect to itunes" screen. so i wait patiently (sort of) through the rest of work, get home and restore to no avail. some error comes up "about sim being pin locked, could not recognize activation, blah" it was rather lengthy, so it's not verbatim. anyway, i feel for everyone who has had tremendous problems/exchanges with the 3g. it's just that the only problem i had with mine (besides this obvious big one) were a couple of iZits. so now who know what myriad of problems i might get with the "white box" replacement. it just sucks. thought i'd share.
