T68i GPRS througput

[KOZAK Imre Oliver]

I bought the phone as Ericsson T68m, for half the price of the T68i. 
That time the speed of GPRS was very slow, almost identical to the 9600 
bps GSM-modem connection, in both direction.

So this is the speed of the GPRS channel:
Somewhat later I have upgraded the phone to T68i software, with the 
latest release. Miracle: GPRS at normal speed. Officially it is 43 
kbit/s at maximum, and varies between 10000-40000 depending network 
usage. Upload is much slower, it can be 13 400 bit/s at max.

Actual data speed is different:
In Speed Download, download speeds are shown as 1.6 kbyte/s, 2.8 
kbyte/s, 3.4 kbyte/s and 4.4 kbyte/s, mostly 3.4 kbyte/s. This is when 
you download a file.
However there is the known delay problem of GPRS - when you query a new 
file, there is a 500 ms lag before the file starts to download. If you 
download one large file, this is not a problem, however, it makes other 
activities quite painful:
- connecting via telnet/ssh to a remote server
- browsing 'portal' type web sites with huge number of small files
Uploading is very slow, I experience it every time I send a larger file 
in mail, or want to update my website. In Transmit, via the sftp 
protocol I usuall get 0.3-0.6 kbyte/s. So I only upload if it is 
emergency.
