I accidentally erased all contents and setting on my IPhone 3g?

[This phone was from the US and "openlined" here in the Phlippines so that I could use it for calling]
Now my phone is stuck on the apple and itunes logo. I tried recovering from itunes on my computer but i get this error 1015. I tried multiple fixes on youtube but still didn't get it to work.

I did the most stupidest thing rofl! I didn't even backup…
Can anybody help me with this problem. I'm really a noob in fixing this kind of problem.

Added (1). All I need is the basic apps like safari, message, etc. I don't need the apps that I've purchased.

Well if you didn't back it up I'm not sure if you can get your stuff back. But, if you hold the sleep button and home button for about 10-15 seconds it should reboot your phone.

Please don't be so self-comdemned! We can't avoid making mistakes. You say you are an nood in fixing this kind of data loss probloem. Never mind, there has been so many iPhone Data Recovery tools to help you recover iPhone data.
What's more, many of them need no speciliazed skill to perform. And it's also OK without iTunes backup, it can recover iPhone contents from iPhone directly.

You can go to google or other search engine to search one. For example, you can search with
" iPhone Data Recovery windowspasswordsrecovery".

Or you can go to the youtube video:
