Planning to switch from 9300 to 9300i

No difference aside from wifi really. A few bits of extra software are bundled in some markets... Bear in mind wifi browsing on the 9300i isn't that great.

I did a swop from a 9500 to a 9300i. Loved the lighter weight and size. Battery life not that fantastic though. It does not last for 24 hours if u use WIFI extensively.

thanks for your replies... i really was seriously thinking if the wifi was worth it... i can surf the net through wap though, so it really isnt much. thanks again!

If you are near a hot spot (home or office) and manage pop 3 mail accounts daily, from the phone, and a lot of internet browsing,it could be an useful switch.

If satisfied with wap/gprs traffic speed makes no sense to switch.
Also, if are purchased software based on IMEi...losing money is guaranteed...

And,

If you are ok with the dimensions go for the admiral ship like 9500 I would recommend it

if you work regularly within wifi reach its much better to have. it would depend on your circumstances but wifi is generally alot cheaper.

I also read the review and am a little confused as I find the browser quite adequate through wifi. Its a bit faster then EDGE and much faster then GPRS and copes quite well. Its obviously not nearly as fast as a PC but seems to keep up with my o2 xda exec (universal) quite adequately (which has a 520mhz chip).

Its also very useful when abroad to have as many connection choices as possible.

IMHO it will be a whole lot more relevant when skype release their symbian client, I understand tuned for the 150mhz cpu in most nokia devices.

In does depend a lot on the sites your browse.

If you can use WiFi for email ona regular basis it is worth it though in my opinon.
