From a comment in the article below:
I installed HTC’s leaked version of 2.2 on my incredible last month. It has been noticeably faster, has better battery life, and the extra features are nice. As expected, Verizon put a lock down on the wifi tethering feature, and if I want to use it I have to pay an ADDITIONAL $25/month, which is completely ridiculous. Luckily, my phone has been rooted (it was the only way to get froyo on there) and I can use a number of FREE wifi tethering applications that don’t cost anything extra per month either.
It’s pretty sad that the only way to enjoy an android phone is to hack the crap out of it, and doing so requires relative technical expertise.
Reminds me of Windows Mobile in another way: the only real fans were those who could play with cooked ROMs. Conversely, imagine if the only iPhone fans were those who jailbroke/unlocked iPhones.
