How to change my password for twitter (I forgot my email too)?

Ok I want to change my username and I use the twitter app so I never need to log out. But anyways I went on the Internet and I tried signing in (using all my emails, and trying any password I use to see if I can sign in but still had no luck for each try).

I want to know my password, obviously bc i want to change it but yeah I don't know what email I used either. The only reason I don't know it is bc I saved it in my phone but sadly later on it didn't save for some reason. I haven't signed in since 3 months ago for my first time so I have no idea.

My question is, since I still want my account, what do I do? Btw I only have an iPhone 4s, no laptop bc a no life loser hacked into my laptop and messed it up.

Using a SIM card from another phone to an iPhone 4s?

So my aunt recently just got the 5s, she's giving me her old 4s. I was wondering if I could take the sim card from my current phone (Some old Samsung phone) and put it into the 4s. Because the iPhone needs an data plan but I don't want to pay for that.

To sum it up, basically I want the iPhone to have the same phone plan as my current phone.
I don't really know much about how phones work so thanks!
