OK, some feedback. iBurst threw the choke chain round me neck with me sitting on 3.12GB (3GB package). So in answering the question on TRYING to play when being throttled = BF2 and BF2142 is unplayable. Ping still around 60 - 80, but unless teleporting while walking has become a new feature in both these, forget about playing after reaching your cap. The normal loading time of a map for a start is about 10x longer. My normal downloads have even gone down from around 100kb/s to 2.2, yes, even worse than dial-up. ADSL FTW! iBurst FTL. What happened to the cumulative cap? I recall on ADSL I could sometimes go up to 6GB without being throttled.
In general, once Telkom can put my lines in, I am going back to ADSL and a netgear wireless router, iBurst modem and external antenna will be up to the highest bidder. I could go weeks without a disconnect, at iBurst I am lucky if I stay on one whole day - this is with an external antenna and an avg of 70 - 100% signal. Way to go boys, good luck for the future. iBurst sounds wonderful and all, but with the amount of trouble I've had with randomly just disconnecting with a 80% signal and many more other probs, I would only suggest using iBurst unless you REALLY cannot get ANY other service. I find their call centre very friendly but amazingly incompetent, uninformed and unadvanced.
Anyway, sorry, I am unhappy and unimpressed cause I can't feed my addiction, maybe I'll feel better when my cap resets - but then the other probs will kick in again.
