I installed on Friday and I really like it. I have had a couple of problems.
1) WiFi: I have a very hard time getting it to connect to my home WiFi using WPA-PSK. At one point it locked up and the only way to clear it was a hard reset. Soft resets put it to the Microsoft splash screen and it never moved past that even after a 30 minute wait.
2) New Messaging Account problem: I can't add another messaging account. When I click on New E-Mail Account anywhere nothing happens.
3) Slow reset: A soft reset takes a very long time to perform.
Other than those problems I have installed the following software and I haven't had any problems:
1) iGuidance 4.0
2) Phatware Phatnotes 4.7.2
3) Voice Command 1.6
4) Microsoft Global Contact
5) Dinarsoft Handyswitcher 3.0
6) VJCandela
7) Total Commander
