2 issues have been discussed (1 confirmed) here:
http://sprintusers.com/forum/showthread.php?t=136071
1) with the touch dialer installed the EVDO connection keeps alive permanently
2) it has a nice sized memory leak, (4mb wasted)
3) and some people have even had problems keeping custom ringtones assigned with it installed.
just wondering how many people are having this issue, and if we can find a way to fix it i love that dialer skin
