I bought my new Ipaq though Tmobile, so far it's pretty cool. I do have a few issues with it, like the phone part getting turned off. I think this is because I have it set to check mail every 4 minutes and it turns on, I'm thinking the phone is getting turned off when it checks mail and is moving around in my case. I also wish someone (safe-net) would come out with a compatible ipsec VPN client. Overall I think it is a good product with a lot of potential.
