I have a week 43 with LCD #5755136 (which is 100% perfect) and also "Firware (sic) version 04.02.13_G" (which is strange).
I find the typing incredibly slow because of numerous mistypes, probably partly due to my large fingers. The fabled "auto-correct" does not appear to do anything at all.
Other than that, however, I am very impressed and pleased with the thang.
i find the auto correct very helpful, i can't believe how fast i can type! Overall the phone is fantastic and the best bit is everyone in my work asking did you get your iphone? Course I did do you want to see it!!!!!!!!
