Verizon Wireless opens network to “Any Apps, Any Device” in 2008
By the end of 2008, Verizon Wireless will open their network to any device which meets a “minimum technical standard.” What that standard is, exactly, VZW isn’t saying yet — that will come in “early 2008.” So any device (including applications) tested and certified in VZW’s new $20 Million test lab is fair game for use on their wireless network. In other words, Verizon becomes the data pipe, and nothing more for these new “bring-your-own” customers. It’s too early to say if this is a watershed moment or not. Verizon certainly thinks so with Lowell McAdam, Verizon Wireless president and chief executive officer, calling it, “a transformation point in the 20-year history of mass market wireless devices.” As usual, the devil (certification fees, turnaround times for testing, those magical minimum technical standards, etc.) might be in the details.
Woo hoo! There’s still the chance that this will be a Darth Vader moment, but it is one tiny step closer to providing me with a cellphone experience that isn’t completely burdened by ridiculously outdated restrictions.

I believe these days Verizon is the only one that really locks down their phones (at least with regards to apps.)
I know I’ve never had an issue with any of my phones on t-mobile, and I don’t think AT&T is any different.
So really, why wait? Just switch carriers! ;)
Literally every single person I speak to on a frequent basis has Verizon. It is far cheaper to stay with them than to be the outlier.
