Is anyone else's twitter app messed up after a jailbreak?

I have an iPhone 4 iOS 6.1. I did the evasi0n 6.1 untethered jailbreak the other day and when I went into my twitter app, it was completely messed up. I'm just wondering if this has happened to anyone else, and if there's a possible solution to it. Also, my weather app wasn't working either. Any possible fixes to this?

Why is LTE on my IPhone 5 so slow?

I got a new IPhone 5 when it came out and everything was working good but now my LTE is VERY slow… When I use the Internet, it doesn't even load up the webpage. I go home and use my Wi-Fi and its all fine (really quick actually) and I change my settings to turn off LTE so it's 4g I think and it goes much faster also. I thought that maybe I should leave LTE off and stick with 4g but when I have 4g I get very low bars.
I also looked this up on the Internet and some ppl had an LTE problem and it was wrong with an antenna or something and they had to replace their phone. I want to know if maybe I changed a setting off or something or if I need to replace something on my phone.

How to delete pictures on my iPhone that I've synced from my laptop?

A long time ago I accidentally synced picture albums on my laptop to my iPhone (I thought it would do the opposite, sync pictures from my phone to my laptop) and it never let me delete them.

What's the best Wi-Fi Hot Spot?

I have a lot of things that need Wi-Fi to work or to be useful in anyway (Ipad, Ipod, Iphone, laptop… Dadadee.) However with the Ipad and I stuff I HATE the cellular data plan, the ones that charge you per GB or MB, I've heard of Wi-Fi hot spots that are cheaper and less irritating however, these hot spots (Boingo, Cricket Cross-wave etc.) have gotten terrible reviews. Are there any good Wi-Fi connectors/hot spots that aren't expensive, annoying or cost by the number of GB/MB? BTW can you get Wi-Fi connection from a desktop computer that's already connected to the internet? If so, how?
