Yeah, I don't have a real big problem with it. At least I'll be grandfathered in with "unlimited" data before there swtich (you would think they would wait till after the 7th), so that is the silver lining to all this. A few days ago, I found the way to download PDANet by pulling my SIM card, connecting to Wifi, and then downloading it, so tethering hear I come.
(I still run stock only because I'm a while weary of voiding the warranty. Plus now I'm waiting for the OTA FroYo anyway, so I'll wait on any potential rooting for a little while).
...and I live near Hartford, so T-Mobile is always a possiblity in the future. Verizon has the "best" coverage, and Sprint has the best bang-for-your-buck plans (plus the Evo 4G tomorrow), but I've always been reluctant to join a CDMA network over a GSM one. Although at&t has been pi$$ing me off lately with their executive decisions (tethering, lack of the android commitment that they said by first half year, the iPhone and Steve Jobs love-making relationship, now the data plan switch). They need to get with it. *gets off soap box*
