Due to restrictions from Apple the bitcoin wallet functionaility is not available in the app store version. However it is still available for free download with limited features.
Maybe you could try downloading it from Cydia? http://moreinfo.thebigboss.org/moreinfo/depiction.php?file=blockchainDp

Yes it does. Go to the down arrow tab, scroll to the bottom of your addresses, press the Scan Private Key button, and up pops the camera window. Aim it at a private key, and it'll be imported. Just tried it myself and the address showed up in my list.
ETA: Maybe I have an old version of the app, not jailbroken.

I tried that, but the Blockchain iPhone app doesn't have an option to scan a private key.. 
I believe you can use Blockchain mobile wallet and scan the private key on your paper wallet.. 
Thanks!
