Thumbs up [ROM] Precision v4.0 Alpha 1 4/5/2011 * It's your phone, use it the way you want *

Built from 2.2.1 XWJS8 source at
  • Features
    - Minimal: only 82MB!
    - Stable: Have tested several apps to ensure it is compatible with everything you use.
    - Fast: I recommend leaving it with no lagfix, you'll get better battery life and you won't notice any difference with it on. It's that fast!
    - GPS: I tested GPS inside my house and got a 10 meter lock within 20 seconds.

Formats DATA, DBDATA, SYSTEM, and CACHE. You can flash over ROMs that use Universal Lagfix such as: Speedmod, suckerpunch, and paragon kernel. Disable lagfix first for extra safety, although not required.

Donations are not required, but if you want to contribute to further developments I welcome anything you can spare.
