iChat to BB question

Currently my wife & I have iPhones and during the work day she uses ichat to sms with me on my iphone. I want to swith back to a blackberry and I am curious to find out if there is a way to do this ichat to bb for texting? I have looked up AIM for the 9900/9930 and it seems like there is nothing good.
Do people think AIM will eventually come to BB or should I look into another chat client (?) to use. we both have gmail accounts so does that help at all? I really like BBM and it seems now you can use it with other people who dont have it, meaning it would use BBM but not actually be BBM if that makes sense.
ANy input is appreciated.
I am looking for a way for her to use the computer and me my phone (hopefully new 9900) to text each other....

You can both use either Google Talk or Whatsapp you can chat to your wife regardless what phones you have with these apps

google talk, whatsapp, msn messenger, yahoo messenger, and like you said you can use add you txtmsg contacts to bbm so its seamless

ebuddy xms just got released on OS7. Looks promising.

Live Profile is also cross platform. It's good.

LiveProfile will have a huge update releasing soon that will take it out of beta and into App World. It already had a bigger userbase than eBuddy soo I'd go with that.

I find it really annoying having all these 3rd party chat applications.

At least with BBM as others have said, you can add a contact as a 'text messaging contact' which will show up as a conversation in your BBM so that you don't have to open up all these separate apps just to see SMS messages.

Whatsapp is what i use to keep in contact with Android/iOS users
