Screen: IP may be slightly better than N97
Operation: As far as I can see from the several models of N97, the operation is really not as smooth as that of IP
Music: The external playback is supposed to be superior to that of N97, and with earbuds, I don't think you need to be skeptical of IPOD's sound quality
Shape: N97 is side-sliding, and is relatively heavy, while 3GS is thinner. The N97 is thicker and heavier, while the 3GS is thinner and feels like a men's machine and a women's machine
(Purely personal feeling, huh)
And the N97 is a full-keyboard, while the IP is a full-touch screen, which depends on which you like
Software: the number of 2 is almost the same, but may be in terms of the game, the IP's boutique a little bit (after all, the Symbian system and his graphics card, which is doomed to not be able to produce the IP's most advanced software. Doomed him not to IP Need for Speed as big as do), but LZ if the requirements of the software is just good enough to use, N97 is also good
Additionally is the most important point is that LZ is whether or not you have the energy to study the Apple system, after all, we are already familiar with the Symbian system, the N97 may not be too much need too long time to get started, and IPHONE is to use the Mac OS which we rarely come into contact with. system, need a certain amount of time to figure out, brush, crack, jailbreak, install software, but now the Internet has been very detailed, give LZ a website, www.weiphone.com
The above comments are for reference only.
Additionally, upstairs, you have to have a limit to black, IP every cell phone, are not easy to die known, you say IP other even if, but that it is easy to die, I can only say that you have not seen the real machine of the black is really sad enough
