So I did this last night, was pretty smooth and simple to do.
Finding apps is pretty easy but seem to be a little pricey for some. Best app so far is the HTC hack for the lock screen to show the time, date and weather. I have an app that shows the weather temp and a little picture of the condition by the battery power.
So far the one that allows me to mod the AT&T logo (MakeItMine) doesnt work and I used an addon to remove the stock clock on the lockscreen but now the damn date shows at the top instead and annoys me
looks like there is almost endless shit you can do to this, but F! wish I would of done this last week when I still had my unlimited data plan instead of paying an additional $20/mo for a tethering package for 4gb
