Wasupwithuman,
Thanks, but I wouldn't recommend using my beta 3.5 rom anymore. The others available on ppcg integrated my fixes and are down to only a couple of bugs.
As for the disabling ev, you can do that through an advanced menu on the phone, but honestly, it doesn't matter. Data usage is data usage when you have this type of phone.
Using other non-pocket pc phones, you could disable evdo using just 1x and teather and be using just plan minutes (free nights and weekends) but the pocket pcs like the 6700 measure all data usage, regardless of whether you use ev or 1x. Honestly there is no benefit in disabling the ev on this phone unless you're on the edge of a coverage area and the phone is constantly searching back and forth which will hurt your battery life. Other than that, don't bother.
I recommend getting an unadvertised plan called the Core Choice plan. Normally you pay 50-60 for an unlimited data plan then 40+ for a calling plan. The Core Choice starts at 79.99 and includes UNLIMITED data and 450 anytime minutes, free in network, nights weekend, etc.
Watch out for those MMS picture messages though & SMS text messages. If you know what you're doing you get con them into giving you free unlimited texting like I did
