Update: this post, based on misleading information from Straight Talk, is incorrect. Based on new evidence it's now believed that the phone uses the T-Mobile network. See I Was Fooled - Straight Talk's Optimus LG 2X Doesn't Use AT&T or Have LTE for the true story on this phone.
Straight Talk announced today that they will be launching unlimited LTE 4G service on the AT&T network for $45/month. Straight Talk's first LTE phone will be a version of the dual-core LG Optimus 2X.
This is the first prepaid LTE service in the US and the Optimus LG 2X will be Straight Talk's first Android phone to use the AT&T network. No word on the phone price or when it will be available. But you can sign up to to be notified of availability at reserve.straighttalkandroid.com
This is a very big deal for two reasons, the network and the phone.
LTE is the newest and fastest mobile data technology to be available in the wild. How fast is it ? Users on AT&T's LTE nework have been seeing speeds in the 15 Mbits/sec range. That's twice as fast as typical speeds on T-Mobile's HSPA+ 4G network and five to 10 times faster than Boost and Virgin Mobile's EVDO 3G
Even without LTE the LG Optimus 2X is a very high end phone. Here are some with specs:
