I'm looking to get a Dell Streak mini 5 used. I had one that was O2 unlocked but it would not data stream but worked fine on texting and phoning. I am on talkmobile. I had a similar problem with a Desire Z earlier this year which, though unlocked, had T-Mobile firmware and so couldn't be used no matter what talkmobile tried to do. Question is............is there any truth in the statement that tablets can't be used on talkmobile phone contracts or is it again the case that O2 firmware is not compatible with Talkmobile? I love the mini 5 what I have experienced of it but it's no use to me if I cannot get my mobile internet.
