What version should I use for Sony Ericsson p910C mytt?

Haha, it cannot be used. In fact, it is Symbian 7.0. The software format should be sis and compatible with java, so in theory, it can be installed in jar format, but, but. . . . This machine is too old. The machine from 2004 has poor compatibility with Java. I have used the p910c for two years. The phone is very good and there are few softwares, such as QQ. Man, I searched online for two years and couldn't find it. If it works well, just make use of it. Use your mobile phone to log in to wap.lelun.com. There are some useful software in the forum. I hope it will be useful to you (by the way, UC Browser seems to be before 6.6, including the 6.6 version). It doesn’t work anymore)
