Here is a little tutorial on how to get a jar application with offline signer for s60v2. Go to http://circles.globe.com.ph/rus929/?s=2.06
Download any app you want on .zip format with ur desktop computer. In the zip file, you will find exp.cer, jar and .jad file. Open the exp.cer then it will prompt for saving. Save it and proceed to the next step. Extract the zipped file and send the .Jar and .Jad file to ur phone on this location C:\nokia\installs\

Go to app. manager on you phone to install the sent .jar app. Without exiting the app. manager on the installed, click option to view the suite settings. You will find out the difference. Hay!!! No more file restriction for .Jar app

If you noticed, i pleaded for help on allowing jar app like opera, mob-rapid to be able to save files. No body helped. I dug this shit out for ya boyz experiencing shitz like this.
For more info, this is my yahoo ID rick_frisk@yahoo.ca

@mafia4lyfe: Don't mind these phone section guys they can be selfish at times. I now know why you didn't recieve my mails, those idiots at yahoo are messing with my mail. Please don't forget the sony ericsson configuration you promised to send.

@hanobaba
Go to internet settings on sony ericsson, create new internet profile. Just give it a name only and select its access point. But make sure the access point selected contains only APN with no ip/port. Just dat. If the access point contains more than parameters, create new access point will only APN and Name as the only parameter entered.
NOTE: The only required parameters to create this internet profile are
1. Name of profile,
2. APN.

You are good to go dude

Thanks man, i'll try it out later.
