The C902 is fantastic, although it doesn’t sync with my iMac. The C702, on the other hand, is proving to be the Joker to my Batman; the EU to my Microsoft; the Creative Zen to my iPod… that’s right – it has become my nemesis.
It’s not that it’s a bad phone. In fact, I’m 100 percent positive that it’s a very good phone. But I can’t test it to find out. You see, the C702 is designed for rugged use, being both splash and dust resistant. You can see that from the moment you look at the phone. The back casing has a little lock that you need to turn in order to open it up.
The problem is, that even with that lock turned into the open position, I can’t get the case off. I’ve pushed. I’ve pulled. I’ve strained and I’ve twisted. I’ve contorted my face with the kind of effort that you generally only get from a bad case of constipation. And even now, the thing won’t budge.
I even did something I hardly ever do – I resorted to the manual. Nothing. I pulled out the M2 card slot cover in the hopes that would make it easier. Nothing.
And so now I sit here, muscles full of lactic acid, fingers cramped into awkward positions, sweat dripping from my brow as I face my nemesis. I am considering drastic measures. Is a claw hammer too far? Or do I restrict my efforts to a butter knife?
At least now I know how they stop the dust and water from getting in. It’s by keeping everything out. Including my SIM card.
(NB – if anybody has any tips for opening the back of this frickin’ phone, I’m all ears)

Monday, June 30, 2008 at 4:58 PMI say keep turning the lock a bit further until it is 90 degrees from the locked position… Just a guess though

Maybe the butter knife is your best bet. Or a screwdriver. That’s one of the only things that gets the battery cover off the handheld scanners at work.
What does the manual say? I recon just keep applying tremendous amounts of force in the direction the manual suggests.
Other wise get a girl to try it. Some of them have a knack for fiddly things that drives me insane!!!

Tuesday, July 1, 2008 at 1:32 AMI have the Sony Ericsson S500i and that was also a pain to take off the cover, it being a slider phone (near impossible when the phone keeps sliding up).
From the looks of the C702, try digging your fingernails (or flat head screwdriver) in between the the top of the cover and the phone. And then push down. (repeat this and hopefully the cover will start to loosen up).
Have Fun.

Friday, July 4, 2008 at 1:31 PMThe toughest phone I ever owned was a Motorola i55sr, nicknamed ‘manphone’. ‘Manphone’ was dropped off of 3 buildings, at heights ranging from 3 stories to 6 stories, and also survived a plunge into a pitcher of beer for 15 minutes. The only reason I got rid of it was to get a phone with a camera (and also to get away from Nextel service!). It took a while to get used to how … gentle … you had to be with other phones.
I specifically bought the c702 because it is a tough waterproof phone. And while I wouldn’t drop it on concrete, off of buildings or into beer, it certainly is sturdy. Including the battery case!
After spending 15 minutes trying to gingerly take off the battery case, I finally put my fingers firmly under the groove just under the M2 slot on one side and the camera snap button on the other and pulled … and NOTHING!
Then I slipped my fingers near the cable connector and yanked up. One little pop later and the back was off. It’s actually quite sturdy. I think my problem was ‘tenderness’. I’m used to these devices being quite delicate.
So, the problem is, you have to BE tough with it. Give it a good yank and it’ll come off.

Monday, August 4, 2008 at 5:08 AMThanks Rhian,
The link was very useful. My experience was the same as Nick’s and the extra knack has prevented me from committing acts of gross violence against Sony designers. Too bad they didn’t see fit to put the tip in the instruction manual,

Thursday, August 14, 2008 at 11:58 PMi had the issue i was pulling the little metal strap holder. It is part of the phone not the cover, make sure the lock is all the way to the unlocked position and then lever underneath the strap holder side of the cover.

Thursday, October 2, 2008 at 9:00 AMdude, all you need to do is stick your fingernails under the case at the bottom end near the little lock and pull it off – no sliding at all. just pull gently and it’ll come straight off.

Saturday, April 25, 2009 at 7:27 PMtrish is absolutely right about sliding your finger in on the side, the case pops off directly, doesn’t slide.
it’s all right here:
