I have got title for my final project : Friends Community Application Base on J2ME For Mobile Phones. This application like friendsearch.com, but i still confused which is most advanted for provider. There are 2 choice : 1. With GPRS Mobile phones must support GPRS and LCD color. To register user must connect via GPRS and then fill the form, fill personal information like name, town, age , sex and user can upload photo. After register user can search friends with specific criteria, like town or other criteria. If user send sms, receiver open inbox and the read sms, user can't directly read sms before open inbox. 2. Without GPRS Mobile phones must not support GPRS and LCD color. But user can't upload photo. To register user send to sms center, example sms to number 3939, and then fill identity. Facility same with upper but can't upload photo. If user send sms, receiver can directly read sms.
I would probably implement the registration by having the user fill in a form over Web or WAP and then send a confirmation message to the phone number the user provided (to which she would need to reply in order to activate the account).
