The Samsung I9000 Galaxy S is expecting its Android v2.2 (a.k.a. Froyo) update sometime in September but if you're too eager to taste the Froyo, you can do it right away since an official Galaxy S test firmware packing Android v2.2 has just leaked.

While some companies haven't even started working on the Froyo updates for their devices, others are, apparently, almost ready to give their smartphones the Android v2.2 treatment. The first Samsung I9000 test firmware with the Froyo on board (called I9000XXJP1) has leaked and is already available for download.

However, before you start downloading the file and start updating your Galaxy S, make sure that you understand that this is a test firmware so some things might not work properly or be missing (for example, there is no Flash support in the web browser yet).

So, if you don't want to put your phone at risk, you'd better wait until September when you'll be able to get the update through the Samsung KIES software.

If you still want to give the test firmware a try, follow that link and read carefully the instructions inside. The I9000XXJP1 is quite stable and is certainly faster than Eclair, but according to the guys who got it tends to slow down when asked to do heavy multitasking.
