This worked for me as well. The version of GTA San Andreas is for a Kindle device so it won't run on a phone but you can still 'purchase' it through a browser.
Look at the Clearwire map in the sponsor section, it's def LTE and you will be able to see all of the other Clearwire towers as well, this map is separate from the Sprint LTE map.
You shouldn't be getting LTE from the clearwire towers until the update comes out for your G2 to turn it into tri-band. Clearwire does have panels mounted on that Wells Fargo off of Huron, but I've gotten LTE from the Sprint Grant tower in that area.
Hey Crimson,
It's path of least resistance, it's typically easier to get permits and easy access to those sites so they upgrade them while waiting for a green light to get to the tougher ones.
That tower has been converted for a few months, I've never seen it lose LTE service since it went active though. If you check out the sensorly (www.sensorly.com) map you can get a better idea of where the towers are active.
