Any good apps in the iOS that aren't boring?

So lately Apple apps are really bad and boring, i used to play a game called cookie clicker (not recommended) and all you do is click a cookie, after a while I got bored of it and couldn't find any apps.

Now I play a game called flappy bird! It's very addicting but so easy to be raged by.
So I need help desperately with apps on my iPhone, Please Help!

How to TRULY delete messages on iPhone?

I'm running out of space on my iPhone. I go to Settings -> General -> Usage to see what I can delete and it says I have 2.8 GB of Messages! So I deleted tons of my old messages. Huge lists of text from old friends and ex girlfriends are gone now… But the number didn't budge! It's still at 2.8 GB! How do you delete these old messages?! They're not even accessible anymore. I've synced it, I've looked stuff up, I've tried everything. How do you get rid of this wasted space?!

My iphone 4 screen won't turn on, even after reset?

The common solution to a blackout-ed iphone screen is to reset it with the home button and the power button, but that wasn't the case for me. I've had water damage on my phone before, but it was fine after being submerged in rice; that was a few months ago. Today, my phone screen went black after a call, and so i tried resetting it. The Apple logo came on the screen, but after a few seconds of waiting, the screen simply went back again. I could receive calls, texts and etc. Again, i tried resetting: the same result came. I don't know what to do )

Do I need a Mac to published and host iPhone apps?

I have a team of developers baking that app for me, and they said that they would post it to the App Store for me. But I have to pay $100 per year just to have the developer account. & I don't own a Mac, so do I also need that to maintain my apps? Because I'm not the actual one developing at, will just have the account.

How to recover deleted iPhone messages without a back up from iTunes?

I accidentally deleted a conversation on my iPhone. And the last time i backed up was in September. So I'm wondering if there's a recovery download that's ONE HUNDRED PERCENT free.

IMessage on mac and iPhone 3

I recently lost my iPhone 5 so i'm currently using the first generation iPhone 3g, which doesn't have iMessage so i use it on my Mac. Until today, i was able to iMessage with my number from my mac but now it suddenly stopped. I have read online to go into settings > messages > then apple id (on my phone) but remember that i have the oldest iPhone 3 and i don't have apple id in my messages tab in settings. Can someone please help me?! I didn't touch anything it just stopped on its own and when i first activated my number on my mac it worked perfectly! I also tried going in messages > preferences and check off my number (on my mac) but my number does not appear as an option.

My iPhone won't connect to my school's Wi-Fi?

I've been using the same Wi-Fi network, username, and password since I came here in July. I got a the new iPhone 5S in December and everything worked fine until last night when my phone randomly logged me off of the Wi-Fi. I use the same Wi-Fi on my computer and phone, and the password/username still work just fine on my computer. I've tried resetting my network settings and logging in various times but nothing works. All it tells me is that I'm using an incorrect username or password, which is not true. Any suggestions on what I can do?
