I never have that issue. I have a sprint diamond on Alltel works for me 100% of the time.
I am working on an update for it now. building test roms all day. Right now I am looking at about 40 updated OEM. a new SYS, a new Manila and everything. it will be a major update.
I am not sure about the new keyboard or not at this time. It works but it has some issues. I think i might stikc with the old keyboard. and if you want you can install the cab that are out at this time.
