HD2 problems

hi i'm new here and hope you guys can help me out with some bothering issues on my HD2. SO HERE'S THE LIST -
1) WIFI- the WIFI is working and it's connecting to hot points, but when the WIFI works the internet connection is down. it wasn't like this till 2 days ago. anyone has a clue why?
2) making a call- when i press send button to make a call the screen shuts down even if the phone isn't near my ear, the call is made but i have to press send again to turn on the screen. than- when i bring the phone closer to my ear it doesn't shut down.
3) SMS- sometime, not in specific time of the day, SMS is going to out-box folder and it's not send even if i try to resend (i'm on Cyta network in Cyprus).
4) Gamil- i defined the gmail account on the email of the device. however unlike Iphone it downloads only headers and i want to see the entire message upon recieving without needing to choose to download it. is it possible?

tnx in advance for all helpers

1) Don't know
2) Make sure you havent installed an app or changed some settings that makes the screen blank when on a call.
3) Install the hotfix from htc's site. Apperantly its not HTC's fault but the network you are on. Most of the people who have trouble with the sms are on vodafone. After many months of research it seems the problem is because of the network settings.
4. First do this:
Press inbox - menu - tools - options - your email account - send receive schedule - download messages - all messages.

Second do this:
Press inbox - menu - tools - options - your email account - download size settings - message download limit - entire message.


Suggestion: look in the settings before asking a question. Most of the apps have a menu - settings or a menu - tools or a menu - options. Always look there and make sure you go as far as possible in the settings so you don't miss out something.

Start - Settings - Today - Items - Unselect everything and select HTC Sense - OK

Just a suggestion when I get a new phone I go through every setting to see what they do.  Doesnt mean you have to change them but you will know which to leave alone and which to change.  I think this is one of the most important things you can do to learn your phone.  I noticed that a lot of your questions could have been taken care of by doing this plus you learn much more about the HD2,  Hope this helps

What do you mean internet connection is down? When you have wifi on don't you want to use wifi and not internet connection? Isn't that the purpose? Turn wifi off and internet connection then takes over.

Not sure what to tell you there if it did work? Install any new apps since it was working? Change any settings on your phone?

To get this cleared up....even though your phone says connected to wifi, nothing actually connects through it?
