Yes. Keep your amp as far from your phone as is reasonable possible. If it's still bad, perhaps you can wrap the the amp in ERS paper or something, since a faraday cage isn't really usable for portable applications.

My Definitive Technology Sub Woofer buzzes just before I get a call on my cell phone if is within a few feet. It's just the nature of the beast.

Just whatever you do, don't put a playing 5G/5.5G iPod with your cell phone; the wheel isn't shielded, so the damn volume goes freakin' HAYWIRE when a call comes through.

The reason is that for those iPod models (I'm not sure about the Classic), Apple decided to make their own click wheels because of production costs or something, and it seems they overlooked that small necessity.

Some electronics are prone to this whereas others are not. My audio stuff is prone to it but strangely my 1967 Telefunken Bajazzo TS 201 radio doesn't really give a care if 15 cell phones are ringing next to it.
Just keep your cell phone a reasonable distance away from your equipment and everything will be fine.

It's just a shielding issue. If the device is adequately shielded, this won't be an issue. If it is not, then it will be.
This is true for headphones as well as amps. My Blackberry drives my Sennheiser PXC350's nuts if the cord is near it. But move the cord just a few inches away, and all is well.

Once heard a case where someone's phono section in their receiver was picking up AM radio so loud it drowned out any album which was playing. Turns out the guy lived like a quarter of a mile away from one of the highest power AM transmitters in the county.
Shielding is the key here, as others have mentioned. Generally, the more you pay for a piece of gear, the better shielded its low-level/susceptible circuits will be. When I still used a cell phone, I couldn't use it near my TV since the picture and sound would totally flip out. The signal gets amplified by the amplifiers and weird interference patterns shine through.
For portable, well thats a tough one since everyone and their momma has a cell phone (or two) in public.

I'm often using my ibasso D10 (being fed by an optical signal form a h140) on the train and I can hear the clicks of cellphones every other second, which is quite annoying.
Do you think it is the amp picking up the signal or the headphone cable that acts as a recieving antenna? Would using shielded cables help? (I am using an ER6i and soon an audéo; any hints on good, light, non-microphonic and shielded cables?)

I've ordered a QB EM Shield for this problem. HeadphoneAddict has mentioned them a few times.
It was only $5.34 shipped, so it's cheap enough to give a shot.
