I have had my i930 for about two months. I travel quite a bit so I really need the GSM feature. Nextel didn't do their regular customers any favors with this phone. I've been a Nextel subscriber for ten years and expected something better. I do have some good news for those owners that are daring enough to do some hacking. Sign on to [...] and pay the nerd that runs the sight $9.95 and you can download a program and a set of directions that will unlock this aggravating beast. From then on it will run anything that runs on any Windows smartphone. If Sprint really intends to continue selling this model they should unlock it. If I had a choice (I use it for work) I'd get rid of it and get something else.
