The Samsung Transform is the latest to get Android 2.2 under it’s belt, not officially, but sort of. SDX Developers member Vampirefo has put all the instructions you need to get Froyo working on your Transform. As always, we feel the need to warn you that any tinkering with the code on your device could make it as useless as tanning bed in Africa.
If you do this to your Samsung Transform and happen to notice any issues, please go to the same forum at the source link below and comment on your findings to help the developer fix any unforeseen issues. This is still in testing, but it is more or less working, even if it doesn’t help your overall speed. Not much you can do there with a hardware bottleneck for specs.
