(keitai-l) Re: N-Gage craxored?

The Nokia Developers Forms are somewhat useful.

Here in the US, unless you setup a 0.0.0.0 (direct) gateway ... apps
that do HTTP I/O will fail after about 12 successful data operations.

In our experience Series 60 devices will pop up a window and ask what
connection to use if there are multiple configurations present on the
handset. For our purposes, it doesn't appear to make a difference
whether we
use a WAP or plain Internet connection (at least via the 4 major UK
network
operators).

This is an area that we have found particularly complicated, and does
not
seem to be well documented anywhere. Does anyone have any leads on good
reliable information on this?

Some carriers support only WAP, not full internet connection.

WAP is implemented on top of TCP/UDP. The device has an IP address and
can
open direct TCP connections. Only the phone's WAP browser needs the WAP
gateway to translate WML into binary stream and essentially deal with
the
WAP protocol specifics, on top of the regular TCP/UDP connectivity. Java
midlets do not use the WAP gateway but connect directly.

Some carriers intentionally restrict traffic, for security reasons or
because they choose to offer different charges for WAP (phone browser,
small
data volume) and internet connections (used for Java apps and internet
access for laptops / PDA as well, in much larger volume). Some carriers
offer only WAP, restricting all connections but the ones to the WAP
gateway.

I haven't verified this, but Series 60 devices seem to route all HTTP
connections via the WAP gateway if it is specified, regardless of
weather
the connection originates from the WAP browser or not. The WAP gateway
often
has a size limitation for the downloaded data, or there may be other
conflict with the operator configuration. Seems like a carrier-related
problem. There are many Series 60 Java applications using HTTP
connectivity
without problems.
