I have been researching tech info about several handsets. Nokia.com has a great info database for developers. But i'm still trying to get some Sony Ericcson handsets info. For example, max Jar size, JSR support, MIDP, and so and so. Beside www.phonescoop.com, is there any GREAT website with this information? THanks

Even spelt wrong the first option on Google is the SE site. Top right side of page has the link to developer info.
Google is your friend.
