All about me: Japanese phone or iPhone 4 or LG Optimus 1????!!!!

HELP GUYS!!!I don't know which phone I should get!!! I like Japanese phones coz well they're from Japan so maybe I'm a bit biased but most of their models are flip phones and I LOVE flip phones!!! I'm currently using an LG Lollipop and I guess it's a flip phone so I should like it but i'm kinda getting bored of it... :p The Japanese phones are like so slim, the screen is SUPER long(which i like :D) and MOST IMPORTANTLy it can type Japanese!!! My Lollipop can't do that :'(

The iPhone 4 has always been my dream phone since the iPhone came out... But then it's kinda big and heavy... And according to the people in my Japanese class it gets heated up really fast but my friend says it doesn't.... So I'm kinda confused... But it can also type Japanese and it has all the cool apps and stuff... But honestly I only use my phone to sms, call and listen to music sometimes... But everyone has an iPhone now and if I get one i'll be like blending in with the crowd... But not everyone has a Japanese phone but i'm sure I won't get the maximum benefits of the phone since it's from Japan and I'm using it in Singapore :((((((((((

Now, the LG Optimus one :) Actually it wasn't even in one of the choices originally. It was actually supposed to just be iPhone 4 and the Japanese phone... But like last Saturday I saw the phone at one of the retail shops... And it looked SO COOL!!! My Mum's also thinking of getting it but I'm not so sure if I want it... But once again the phone is kinda big but it's a touch screen... And I like touch screen phones... But I'm not so sure if it can type Japanese but apparently there's one cool thing it can do :)) I can literally say the message I wanna type and the phone will automatically type it down!!! AWESOME RIGHT???!!!?!

Ok so I really don't know which phone to get but I still have until Christmas so... yeah... But I would appreciate it if u guys would comment and tell me which phone u recommend and the reasons if u can :DDDDDDDDDD Thanks :)))))))))
