After you get that done, you will be able to do alot of what you have complaints with. Mywi will solve your tethering problem, and there are themes that you can use to get a more custom look. If you want to go far enough with it you can even get quasi HTC sense widgets (I have not done this, but have seen it).
Lots of other features out there in the jailbreak world. Give it a look.
I highly recommend doing it. It is as easy or easier than the rooting most of us are familiar with.
I've heard 4g is on hold. The whole Iphone deal cost them a bit and since samsung was there 4g partner they got a little upset about them getting it. But that's just the latest in the rumor mill.
I'm sure that is part of the reason 4G is on hold, but seems like this interoperability debate could be playing a big part in it... if there isn't interoperability with bigger carriers (for 4G roaming), then that will put a kink in things for CS and other small carriers... unless LightSquared can get their FCC approval and win the argument with the GPS industry... geez, what a mess.
How do I install Cyanogen Mod on a Cell South Milestone (not Milestone X)? I'm rooted, but cannot find Rom Manager Free on the Market or in Appbrain any more. I purchased the premium license, but no free version is available to use the license with. I had it installed a while back, but it never would allow me to flash a Cyanogen Mod nightly, so I deleted it. I was going to try it again. I'm bored with 2.1.
