Samsung :: SMS Limit On A Vice (R561)

I've been trying lately to change the SMS char limit on my phone for a while now, but before I get into that, let me give you some background to why I'm doing this.I use to own a old Samsung phone, I can't remember the model, but I loved that phone! Best phone ever, anyways It had a SMS limit of 160 chars per text which was great, but the phone broke, it got ran over, and ever since I've never been able to get a phone like that one. So I'm using a vice now, and I like this phone as well, but it has a 140 char limit. Now What I'm trying to say is I looking for some support on how I can increase that limit to 160.

I've been looking around, and I'm not trying to put illegal software on the phone, more like modifying the firmware or software on the phone. This isn't a smart phone else I would get some app for it, plus I don't want to pay paying for a data plan for SMS when I have unlimited text messaging on my phone. I know this sounds dumb, why not just send 2 messages, well here the other reason, my friends all have phones that are 160 max, and my phone loves to spit them, and its so hard to read them, and I'm tired of this. This is not a network restriction as they also are on the same network. This is a phone lock down of some kind. Anyways enough ranting for me, this is what I've done so far. I've gotten my computer to read the phone using QPST, I do have the SPC, and I can change the system on the phone. All I need now is someone who knows little more then I do about this, and how I can modify this SMS limit, and make it 160 instead of 140. For both sending and receiving.
