may i know does the skype work in so?

Petro/SO data has to go through Rogers WAP proxy server (goam.com APN). Your data doesn't go directly to the internet. It first goes to the proxy server. The proxy server reads your request and then makes a separate data request out to the internet. The WAP proxy server is designed to allow dumb phones to access the internet. Dumb phones can't do big downloads and don't have big screens. The WAP proxy server tries to shrink images and reformat web pages so they can be displayed on a smaller dumb phone screen.

That's why there is a time delay and throughput hit because the WAP server has to analyze the data being sent to you to see if it should be reformatted There is probably has a max file size that is allowed by the proxy, so a big file request is split up into many little file requests.

For inbound Skype, the proxy only maintains a network connection for a few minutes and then terminates it. The same thing happens with push mail (gmail, hotmail, etc). It works for the first few minutes then stops. The proxy server disconnects (which kills inbound data) and waits for the phone makes a new outbound request that then restores the connection.

Skype works better for outgoing calls, but it doesn't seem to stay running for incoming calls.

Beside, messaging is fine voice is at best iffy.
