What to get a 10 yo boy for Christmas?

My little brother is beyond hard to shop for and isn't helping at all. He's pretty set for electronics, my mom got him a ps3 and I got him an iPhone (no service, only used for games and internet) for his most recent birthday. He's pretty sporty and loves out doors and that kinda thing. I already bought him a robot model thing and oil pastels because he really wanted a set, bit I need something for his "big" main present ( Around $50-75). Any ideas?

Really weird problem with iPhone 4s with Sprint?

So for the past few days, my iPhone hasn't been working right. First, I can't text anybody without an iPhone, otherwise it'll give me a text saying "You have this number on your blocked list" when I obviously don't have that person on my block list. I've even checked 3 times. Then, my phone completely refuses to connect to the internet or allow mew to text ANYBODY when I'm not in Wi-Fi. It'll tell me "Couldn't activate cellular data network. You are not subscribed to a data network" I'm just wondering why this is happening? I've tried turning off Wi-Fi and my cellular data settings and then turning them back on, turning my phone off, ect, and this problem is still occurring.

I dropped my iPhone 4 into my bath

Well it fell in, and it was probably submerged for 3-4 seconds before I jumped out panicking. I immediately tried turning it off yet the screen wasn't responding so I couldn't slide to power off. I blew into all the open slots in it, and shook it about a bit. I used all the rice I could find in my house and put my phone in it. I can hear it making a small ticking noise every 2 seconds or something. I'm Really worried, as my parents are ultra mad at the fact that I'm so irresponsible. Is there anything I can do? :'
