Anyone with a Samsung Galaxy S might find this a little interesting. The great minds from XDA developers have posted on their forum the Android 2.2.1 I9000XXJPU Froyo build, specific to the Galaxy S. It's said to fix plenty of issues that the Galaxy S had with Froyo, making the device faster and lag free. In addition to a lagless device, the new leak also adds various new features and bug fixes including:
- 339MB free RAM because of reduced drivers footprint
- improved UI speed
- improved browser speed
- reportedly improved GPS and video player
- OTA (over-the-air) updates, however it is not known if this version will receive any.
- ability to change lock screen wallpaper
- swype version 188.8.131.5271 with the following languages:
- US English
- UK English
- and more (reportedly Ukrainean or Korean)
Since this is not an official release, there is always the possibility of damage to your device, so proceed at your own risk. One issue already reported with the upgrade is a missing backup/restore to sdcard function.
