I have the BB 8320. Can anyone tell me though - since I find this very confusing - if I should be using the GPRS or WIFI setting if the latter is available. What's best??
GPRS and Wi-Fi are two ways of getting data (especially email and the web). The main difference is :
Here are some elements for you to understand why Wi-Fi is better : these are the max download speed, by network system (higher is better) :
About the Wi-Fi coverage, there should be some black and white picture Wi-Fi indicating whether there is Wi-Fi nearby. You can also buy (not from Blackberry) many gadgets to detect Wi-Fi networks. Be aware that some Wi-Fi hotspots are free (McDonald's, Starbuck's), and others require charge (some airports). GPRS on the other hand is available averywhere except maybe when you go to the country far from mankind (can happen on some highways), but you'd be extremely lucky to have Wi-Fi and not GPRS.

Thanks so much for that. Very helpful. Another question if i may...what about Edge? The spec for my handset mentions both GRPS and EDGE. How would you go about connecting through EDGE? I have spent so much time on the phone with my service provider and it takes forever to get the right answers cos they keep putting u on hold to chat with other departments cos they dont have the answers!
Your help is much appreciated.

Your throughput values for WiFi are misleading. I have a WiFi test driver that sends data over WiFi to a TCP server on my computer (on the same LAN). These are ideal conditions with VERY short round trip times. Performance drops off dramatically when the device is connected to a server on the Internet.
Average throughput for WiFi on an 8820 is approximately 200 KB/s or 1,600 kbps. Here's some graphs that illustrate throughput for various amounts of data transferred for different socket send buffer sizes (8 KB -> 128 KB).
Under tiny workloads (i.e. an email) WiFi can achieve a throughput around 950 KB/s or 7,600 kbps. Throughput quickly drops off for higher volumes of data.

Thank you for your time, eaolivier ; The technical information you provide is very valuable. I wanted to give theoritical datas for the diffferent networks, but it's true that Wi-Fi theory is very different from what can be observed in real life.
Including your remarks, here is a modified version :

I have found a speed comparison of the browsers of a 8300 (EDGE) and of a 8320 (Wi-Fi) on boy genius report. Basically, EDGE is as fast or faster than Wi-Fi for browsing the web.
Here is the link :

from a technical point of view, I cannot agree more. But from a user point of view, Wi-Fi is just a pipe to get things : email, webpages, downloads, and that's about all.
Yes, I saw that when it was released. However, loading webpages is not an accurate way to measure the throughput of a wireless technology.
