Here's an update. My friend bought a new Samsung S3 yesterday for approx $300 plus tax, that includes 2 separate $50 discounts (instant & rebate). I also installed the minor upgrade from Android 4.1.1 to 4.1.2 (if I'm correct). I then installed both FoxFi and PdaNet+ to the S3 phone, and yes the apps work for wireless tethering! My friend was able to wirelessly tether to a Windows laptop and an Android tablet. I just wish the MetroPCS "4G" network was faster and with a stronger signal. But it's good enough for streaming YouTube videos, but not strong enough to stream movies using the TV Portal app. Oh well, at least it works! The nice thing is that MetroPCS only charges a measly $60 monthly bill for UN-limited everything! That price includes tax too! Pretty much can't beat that price anywhere! But as you probably already know, the major downside is that MetroPCS has limited coverage areas, plus they never have the new phones until many weeks/months later.
