Hello, i am away from my Home for some days. Hope everybody is fine on this forum. i am to ask that i am using Nokia 7610 and i want my MIDlet to install on this mobile phone. i simply put jad and jar files into memory card and used file manager to install. but it gave the following error message "Invalid verson can't install". please tell me if some Softwares need to install or what should i do. Thanks in advance.
