I want to start working on J2ME not just along with emulators but also on the real phones.
Can anyone pls suggest me which kind of phone shall I/any developer purchase which provides me to upload my stable full blown application on them?
Thanks in advance.
A phone which supports the J2ME specifications you will be targeting and which supports all the features you will be needing.
So good luck researching what possibilities you have and what features those possibilities have! You may want to start going to the websites of popular brands and see what they have to offer, but that is so incredibly obvious I'm sure I don't have to tell you that.
