I hear there are problems with this device on the T-Mobile network. Can
anybody here confirm this?

I'm debating whether to get a Glofish M700 or the HTC S730, which should
be here (UK) by first week of December. It's a faster version of the
S710 with a few extra features, and apparently everybody who has a S710
absolutely loves it.
