A BlackBerry for business use during the day... A regular ol' cellphone for use in the evenings... What a novel idea!
Don't get me wrong now. I LOVE my BlackBerry. But sometimes I wish I could put it away and use one of those regular, slim, fit in your back-pocket cellphones for the evening!
Perhaps I'm ignorant or un-educated on the matter, but I did some research today, and it turns out that most US carriers allow you to do this! Yes, 2 devices on one plan is feasable, while it IS easier on some carriers than it is on others.
I haven't found whether this is possible with the major Canadian carriers yet, but it is something I'm looking into.
If you're in the US and would like to know if running 2 devices on one number is possible, check with your carrier.
