How to get t-mobile on my iPhone 4? - 1

I do have a t mobile SIM card. But my iPhone 4 does not have a slot for it. There's no hole at all on the right. There's one on the top, but there's no outline of a slot. It's just a random small hole. If someone can tell me how to do this it would be AMAZING. Btw, my iPhone is jailbroken. If that has anything to do with it.

IPhone app for photos slideshow?

Not really just a slideshow but more like an animated gif. I held the capture button down while taking pictures so I have a collection of consecutive photos. I was wondering if there's an app that I can put those in and it will play them like a video or like a flip book

How to use effects in snapchat?

I have an iphone 5s and whenever I type negative… Sepia… Or b&w… Nothing happens to the photo. My friend has an android phone and they always work when he does it on snapchat. Do these effects not work on iPhones?

IPhone speaker sounds crackly?

I'm using iPhone 3Gs. I got it since 6th Grade. Now I'm in 8th Grade. My iPhone often drops in the past. I bought an Android and I didn't used it for a couple of years. Now I'm using it I noticed dirt/dust in my speaker. Is there a way to get rid of this issue?

Should we start a class action lawsuit against Apple?

I bought a refurbished iPad mini on Ebay. However, I can't use it because it already is linked to some one's Apple ID. The seller has so far ignored my requests for information to address this. I have been researching this issue online and it turns out a ton of people are in the same boat, getting iPads or iPhones that are useless, except as paperweights, because they are linked to an account with a password that the person does not have, or has lost.

Now, you may say, "Oh, this is good because it deters theft." However, I'm not saying to make these tablets totally open without password protection. However, each of these iPads surely has a unique signature / code embedded in it, likely linked to the Apple ID needed to activate it, and to contact info for that person. It would be a piece of cake to simply enter that unique signature online, and see if anyone has reported that iPad lost or stolen. If not, after a period of time, the iPad should be unlocked for the new owner.

This is a big deal because it is frankly a blight on society when productive resources are turned into useless junk. All the iPads and iPhones that are perfectly functional, but for this activation lock, is a terrible waste of the Earth's scarce resources, and just makes no sense, except in the eyes of a corporate profiteering point of view (i.e., thinking the more iPads that they sell that become unusable, the more additional iPads they can sell).

I'm thinking a court in law, or perhaps even in equity, ought to be able to provide some relief from a policy that is so short-sighted and represents a form of bad faith profiteering. At a certain point, bad customer service crosses the line and becomes an unfair / improper business practice, and I think this should qualify. Or, even better, Apple executives should get off their *** and do something to address this. It's a simple, common sense fix for a prevalent problem.

IPhone won't show up in iTunes?

I recently updated my iTunes on my computer and my iPhone 4S to the 7.4. Now I'm trying to sync my phone to iTunes on my computer and it won't show up. It pulls it up as a file of internal space on my computer. I have rebooted both devices with no success. Any suggestions?
