I renewed my wireless plan yesterday and in doing so picked up a new Motorola V551 which is Sun Java and Bluetooth enabled. My question is will the J2me Wireless Toolkit 2.2 be enough to get me started learning or should I find a motorola specific development kit and use that instead?
Yes, it should be enough. Preferably with a decent IDE (E.g. Eclipse with the J2ME plugin).
However, if your only developing for a specific mobile phone, you might as well find the it's SDK and emulator. That way, you won't (read: shouldn't, in theory) get any problems when you try to run it on your mobile.
