when i was using edge.. simple download (like downloading applications like CCleaner).. i would get true edge speed (15-25KB/s). And i made it a habit of not running other internet-related programs while downloading. At least if i had to, i would open 2-3 pages while downloading (upgrading i-tunes while surfing web 2-3 pages, i would get 10-18KB/s). On average, 15-22KB/s. More than 22 like 26 or 27.. i would be happy

. less than 10.. aint good, though sometimes, certain sites seem to be the culprit. Though i believe, edge could be higher than what is being offered. These are all my readings for almost 2 years on edge at Taman Maluri.
I ve never used modem, all using Nokia phones since sim card is attached to my phone lines and makes em easy for me to be really on the go. 6630, 5500 Sport, N80 and N82. ( i prefer Nokia since their Pc suite is easier for me to configure than SE). Using 5500 i didnt get true speed of edge since it was only class 10 edge speed. N82 wins over with class 32 edge speed (plus 3.5g ready).
Even on edge, my bitcomet (errr... my brother used em..

lol) i would get a constant 10KB/s and if downloading while sleep.. i ll get 17-25KB/s
Facebook, by nature is a bit slow, but not to the point of extremely slow. But then again, maybe, you are used to 3g/3.5g speed, thus edge speed is unbearable to you. I, on the other hand, has been living on edge speed, thus 3g or anything higher is like... OH MY... Ooooo La La!! lol

Basically, you should get a speed of 10-25 with 15.16.17.18 being on average. Normal surfing, 2-3 pages open simultaneously, faster that way. You tube.. aha? dont expect the click n play.
Zwanvedder,
i might... i might... , time for a change. huhu.. We will see how things turn out
