How to upgrade iphone memory?

I have a iphone 4 8gig is there a way to physically add more memory. Is there an sd card built inside of it that can be removed or is just internal memory built into the mother board?

There's no way unless you get a new device.

Yes. Hook up your iPhone into iTubes on the Computer and save EVERYTHING to it. Go to a store, and go but a higher-class more storage iPhone. Then, plug-in your new iPhone to iTunes and download all of your things back. Sorry the disappointing news about getting a new one. But. Hope I helped. ッ or. Maybe try to take out the memory card by screwing out the bottom screws, and pull the back off. Order a new chip and switch it out. Or like I said before buy a new one but SAVE EVERYTHING.
