It is suggested that 5530,5530 is much more cost-effective than C5. Not necessarily a virtual keyboard. Touch screen games are now very mature, and gravity sensing games are also very awesome. As my friend upstairs said, WLAN is very common and practical, not as far as 3G. Most importantly, the full touch-screen mobile phone must be the mainstream of the future, and now it can be clearly seen. You buy C5, but it's just an ordinary mobile phone. It doesn't make any sense at this time, so it is suggested that 5530 is the best choice among the two mobile phones with similar prices. It's been used for half a year, and it feels good.
