Will rooting my HTC Incredible 2 allow me to switch carriers ? If not does anyone have any information on how to unlock my phone from Verizon ??
CDMA carriers tend to not allow phones from other carriers to operate on their networks. There is not a way to get your Incredible 2 to operate on another network. Rooting your phone will have no affect on this.

What CDMA vs. GSM Means to You
For call quality, the technology you use is much less important than the way your carrier has built its network. There are good and bad CDMA and GSM networks, but there are key differences between the technologies. Here's what you, as a consumer, need to know.
It's much easier to swap phones on GSM networks, because GSM carriers put customer information on a removable SIM card. Take the card out, put it in a different phone, and the new phone now has your number. What's more, to be considered GSM, a carrier must accept any GSM-compliant phone. So the GSM carriers don't have total control of the phone you're using.
That's not the case with CDMA. In the U.S., CDMA carriers use network-based white lists to verify their subscribers. That means you can only switch phones with your carrier's permission, and a carrier doesn't have to accept any particular phone onto its network. It could, but typically, U.S. carriers choose not to.
In other words, you can take an unlocked AT&T phone over to T-Mobile (although its 3G may not work well because the frequency bands are different). You can't take a Verizon phone over to Sprint, because Sprint's network rejects non-Sprint phones.
