This is the new Samsung Admire 2 4g LTE. It is pretty spanking new (so much so you don't have any forum slot, or phone listing for it). Its designator is SCH-R830C, and Antutu benches (stock) at over 10k.
The CPU is listed as "Samsung Infinite" (via Antutu)
Its a dual core ARmv7 snapdragon
with a ADRENO 225 GPU
4gig ROM 1gig RAM
up to 64gig on SD
2100MAh battery
Beam/Near Field, bluetooth 4
plus all the usual Samsung bells/n/whistles
For the OP the cricketusers forum has a method to unlock the phone.
It would be nice to have a subsection set up here though, as this phone is such a hot seller (cricket in-store pushed it out at 50$ and it sold out so fast that they can't get them back in stock.) Currently the phone lists for 279$, but online cricket is selling the device at 99$.
It appears to be a bog-standard samsung galaxy type phone, and for a mid-range device, damn snappy. Just picked one up as well....that price was too good to pass up on.
