I downloaded and restored custom ipsw via iTunes 9.0.1 Now shows: Ver. 3.1 (7C144) 04.26.08 BB.
I downloaded and restored custom ipcc because iTunes would not give me the official AT&T carrier update. Now shows: Carrier AT&T 5.5

when I try to send a picture message it stalls out just before the progress bar finishes and then says cannot sent. I can still send regular text.

AT&T says my phone is provisioned correctly.

Any Suggestions. TIA
