No, not necessarily! The antenna already supports 3G in 2100, 1900 and 850 mHZ - besides GSM at 850, 900, 1800, 1900 mHZ! So for the antenna to support a frequency in between, is no problem!
BTW
The iPhone4 unlocked is also avalible in Denmark, for purchase at the ridiculous price of €625 for the 16GB version, and €730 for the 32GB version!
