[Q] I need to redirect all calls and sms from a blackberry to another

First of all, thanks for reading and sorry if I am in the wrong thread, if so, if you can point me which forum to go, I'd appreciate it.

Long story short, I have two blackberry, one for personal use and one for work, problem is that I need to get out of town for a few months and I dont want to bring both phones with me, so I am looking for a way to redirect all calls and sms to my personal phone, a friend of mine will have my work phone to recharge it or in case anything happens but I dont want him to manually send me all sms and I dont want to text anyone from my personal number to not confuse them (it should appear as I am texting from my work phone)

Here another problem: my friend doesnt have internet, I can easily redirect all the calls to my personal phone but not sms, at least not without an app that requires a wifi connection

do anyone have any idea what can I do ?
