Restricting data usage with jailbreak

I'm looking for a solution for this as well. I've only a limited 10mb data plan and I'm planning to use it only for iMessage. Any updates?

 

Yeah good luck with a 10mb plan on an iPhone.
You will use that up in 2 minutes without even doing much.

 

Indeed, I dont really use up much of my 2g plan, I get to about 700-800mbs each month, but 10-20 is not very realistic, you would reach that limit in a week regardless of what you do..

 

Check out Onavo at http://www.onavo.com/. I have never used it but heard about it a few months ago.

 

Well yeah, but I'm roaming and 10mb data is the most I can afford at the moment so I don't really have much of a choice.

Thanks for suggesting Onavo. Unfortunately, it isn't what I was looking for. Rather than a data limiter/tracker, I'm looking for a firewall-like solution where I can choose to allow only certain applications traffic. I have tried Firewall IP, but it doesn't completely fulfill that purpose. There're still some rogue processes in the background taking up 1mb every few hours.

I need some fine grained control so that I can make the best of the 10mb I'm given.

 

Try Firewall iP in cydia. Block all outgoing/incoming connections except iMessage port.

 

I was just about to suggest this as well, Firewall IP works perfectly for me. Onavo is also a good thing to have if you really want to save on data. The few times I tried it, it definitely helped conserve how much data I was using but did not work properly 100% of the time. That was in the week it was first released so I'm sure the bugs have been worked out by now.
