I've got an I5510L...I was trying some user-made CM7.2 and CM10 ports... the only problem so far comes from the hand of samsung not realeasing up-to-date source code of the Kernel of I5510L (LCD driver gets modified from I5510 to I5510L), so sometimes those Kernels give me a pain with the screen. I asked samsung for the Source files, and they answered back saying that tehre was no 2.3.6 for I5510L, wich is a lie because there was a 2.3.6 release for Venezuela region :/
I'll have to ask the wizards and see what can they do...
