Replying to Blackberries, decision making. Apps and such.

So, I have searched and nothing really came up with an answer. So I decided to get a Blackberry. My phone company Telus, discontinued the Blackberry Pearl, because of the pearl flip which is what I was going to get originally, so I found a new one on eBay for $200 cheaper than at the store. So now that is on its way being shipped here, I start looking at apps and stuff I could get. However, i haven't found anything on this, but do pretty much all the apps in the BB app store work on Pearls (the non-storm ones of course) or no? Because everything I read seemed like it mentioned the Curve or the Tour or the Bold and not the Pearl. I guess I don't really want to get a phone that is going to be completely outdated and not fun to have in 3 months. I would get the Tour but the cheapest ones I could find were like 400-500, and I kinda break alot of phones (like 7 in a year), so I dont want to go all out on a phone.
