David Fitzherbert was skiing off-piste down a glacier in the Matterhorn and Monterosa peaks in Switzerland when the snow gave way.
However, he got caught between the two rocks due to the 1/2inch-wide Blackberry in his breast pocket.
"The snow gave way beneath me and I fell down a very deep crevasse," the Sun quoted Fitzherbert as saying.
"After 70 feet it narrowed and I became stuck like a cork in a bottle between the walls.
"Fortunately the extra inches of the Blackberry were enough to block the fall," he added.
Fitzherbert broke his jaw, smashed his teeth, cracked a bone in his chest, and nearly tore his nose off.
His mountain guide made a distress call, and a mountain rescue team came to dig him out.
"I was stuck so fast they had to get a drill to dig away at the ice around me. I was eventually winched out by the helicopter rescue team," David added.
