Any decent app, or Cydia store app will let you download and install the purchased apps again for free. Up to 4 devices usually.
Just login with the same info you used when you purchased it (Facebook, Google, or Amazon) and it will recognize that you've already bought an app and let you download it free.
As for QuickSMS, the paid program is a trial, you can download it and use it for 14 days for free, but then it disables itself until you buy a license.
