So this is my first real jalbreak experience and I'm surprised how many mods require a payment. So if I wanted something like Intelliscreen how do I pay for it? What happens if I need to wipe my phone or restore it? Do I have to buy it again?
Same goes for BiteSMS. I downloaded it but didn't realise it's basically a trial version. Can I continue using it after the trial ends? Tbh I like the app so much I will probably pay for that one
Payment is through Amazon or Paypal, but authorisation can be through either a Google or Facebook account. They're linked together, so if you, say, get a new phone, if you go to "Manage Account" on the main Cydia screen and login with the associated credentials (I've only used Google) it'll show you the items you've bought under your account and will let you download them again if you want.
They're not device-restrictive either, so there's no problem with you using the same account on an iPad and iPhone at the same time, for example (like I've done and can vouch for).
