I am considering Nokia C3-01 and SE Elm.

What I like on the C3-01:
Slim phone
3.5mm jack port

What I dislike on the C3-01:
Slow processor (Based on reviews)
Slow or unresponsive touchscreen response (Based on reviews)
Complicated Interface [Menu leads to menu which leads to even more menu.. (Based on reviews)]
Doesn't really like the user interface. (I am not sure it could be customize to my liking)

What I like on the SE Elm:
Faster response and interface (I am not sure about this, but there isn't really some complaint about it response in reviews- Need some clarification though)
Simple Interface [(Based on reviews.) From what I see its menu is quite organize and I could access to them quite fast too]

What I dislike on the SE Elm:
Its contour [I am afraid that it will be hard to grip(Need some user comment on this)]
No 3.5mm jack

Btw, I am kinda confuse with these two phone 3G connection. At GSMARENA, for the SE Elm, it only support HSDPA 900 / 2100 but the C3-01 has support for HSDPA 850 / 900 / 1900 / 2100

I am not sure on what is the difference between the HSDPA, could anyone enlighten me?

One more thing, the SE Elm do include a adapter to connect 3.5mm jack? If so, will the adapter restrict better performance of a better earphone?

Thank you for reading, please give some advice.

Currently, is our mobile operator using HSPDA or UMTS? Btw, how fast are the HSDPA 850 / 900 / 1900 / 2100?

Anyway, since the Elm only support HSDPA 900 / 2100, if our mobile operator uses HSPDA 850 / 1900, the Elm couldn't get the 3.5G connection?

Smartphone might be a better choice, but I have limited budget of 500.

Oh, thanks.

Btw, could you recommend me a RM500 smartphone. I prefer 1st hand ones as there are longer warranty and less hassle.

Thank you for the suggestion, but neither of those has Wi-Fi connection. Btw, I have no preference on brands. Could you recommend me other brands as well.

Thank you for your suggestion, but I think I will go back to either Nokia C3-01 or Sony Ericsson Elm.

Btw, the SE Elm will be able to support the 3.5G connection available on our mobile operator?

SE Elm @ RM481 VS Samsung Galaxy Mini @ RM570

Any opinion in both of them?

For SE Elm.
Camera is better than SGM.
GPS Navigation System is trial version. After that need to use GPSMid that uses OpenStreetMaps. Anyone tried it before?
SE Elm doesn't have 3.5mm jack.
Cheaper.

For SGM
Could use Papago that use Malfreemaps.
Does have 3.5mm jack.

My main concern is with SE Elm GPS Navigation after the trial period, if there is a good substitute for it, I would take that model.
